Check the car's build date on the door sticker: I'd bet serious money that it was built between January and March (including March) of 2013. Those early build packs apparently used the old 2011-2012 battery chemistry, albeit in the same new package as the rest of the 2013 cars, and they lose capacity fast.

Sigh, wish I had seen this info sooner. Thought I did enough research before buying my 2013 Leaf this past weekend, knew I wanted a 2013 but didn't realize how much build date matters. I got one with a 3/2013 build date.

I was responding to Swamibob, whose Leaf had l dropped to nine bars at the time. If your car has lost only one bar, it's at least possible that yours was built right at the end of March, and got the newer chemistry...

2013 "Brilliant Silver" SV with Premium and no QC, a 2009 Vectrix VX-1 W/18 Leaf modules, and 3 EZIP E-bicycles.PLEASE don't PM me with Leaf questions. Just post in the topic that seems most appropriate.

Oh I hope I didn't come across as blaming anyone! Just bummed at myself, I thought I had all the info and was ready to buy.

Is there a definitive way to know which battery pack/chemistry a vehicle has?

From my understanding there are three variants of battery in the 2011-2015 (2016 S) cars. I know of Gen 1 (2011- 3/2013) Gen 2 (3/2013 - 2014) Lizard (2014-current as a replacement)
